Designed for various specific and general purpose application such as; output and
driver stages of amplifiers operating at frequencies from DC to greater than 1 MHz;
series, shunt and switching regulators; low and high frequency inverters/converters
and many others
Features:
Very low collector saturation voltage
Excellent linearity
Fast switching
PNP values are negative, observe proper polarity
